2016-05-09md: raid10: add prerequisite to run underneath dm-raidHeinz Mauelshagen
In case md runs underneath the dm-raid target, the mddev does not have a request queue or gendisk, thus avoid accesses to it. This patch adds two missing conditionals to the raid10 personality. Signed-of-by: Heinz Mauelshagen <heinzm@redhat.com> Signed-off-by: Shaohua Li <shli@fb.com>
2016-05-09md: md.c: fix oops in mddev_suspend for raid0Heinz Mauelshagen
Introduced by upstream commit 70d9798b95562abac005d4ba71d28820f9a201eb The raid0 personality does not create mddev->thread as oposed to other personalities leading to its unconditional access in mddev_suspend() causing an oops. Patch checks for mddev->thread in order to keep the intention of aforementioned commit.

2016-05-09[media] c8sectpfe: Rework firmware loading mechanismPeter Griffin
c8sectpfe driver relied on CONFIG_FW_LOADER_USER_HELPER_FALLBACK option for loading its xp70 firmware. A previous commit removed this Kconfig option, as it is apparently harmful, but did not update the driver code which relied on it. This patch reworks the firmware loading into the start_feed callback. At this point we can be sure the rootfs is present, thereby removing the depedency on CONFIG_FW_LOADER_USER_HELPER_FALLBACK.

2016-05-09mfd: vexpress: Add !ARCH_USES_GETTIMEOFFSET dependencyArnd Bergmann
The MFD_VEXPRESS_SYSREG driver selects CLKSRC_MMIO, which in turn conflicts with ARCH_USES_GETTIMEOFFSET, causing a harmless Kconfig warning when it is set: warning: (ARCH_MVEBU && ARCH_DIGICOLOR && ARCH_GEMINI && ARCH_KEYSTONE && ARCH_MOXART && ARCH_MXS && PLAT_SPEAR && ARCH_SUNXI && ARCH_TEGRA && ARCH_U300 && PLAT_ORION && ARCH_CLPS711X && ARCH_EP93XX && ARCH_NETX && ARCH_IXP4XX && ARCH_KS8695 && ARCH_W90X900 && ARCH_PXA && ARCH_SA1100 && ARCH_OMAP1 && ARCH_BCM_IPROC && ARCH_INTEGRATOR_AP && ARCH_OMAP2PLUS && MFD_VEXPRESS_SYSREG) selects CLKSRC_MMIO which has unmet direct dependencies (!ARCH_USES_GETTIMEOFFSET) This was apparently hidden by the fact that no ARM platform that still sets ARCH_USES_GETTIMEOFFSET has gpiolib support, and we already have a dependency on GPIOLIB that I added a while ago. However, after 296ad4acb8ef ("gpio: remove deps on ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB"), any platform can enable CONFIG_GPIOLIB, and that lets us enable MFD_VEXPRESS_SYSREG as well. This adds an explicit dependency on !ARCH_USES_GETTIMEOFFSET to guarantee that we can enable the CLKSRC_MMIO driver without getting warnings.

2016-05-09arm-ccn: Enable building as moduleSuzuki K Poulose
arm-ccn driver uses irq_set_affinity, which is not exported and hence cannot be built as a module, eventhough we have all the bits ready. This patch makes use of the exported helper irq_set_affinity_hint() instead. Also, the __free_irq expects the affinity_hint to be NULL when we free the irq. So set the affinity_hint to NULL at clean up. Now that we can build it as a module, update the Kconfig to reflect the change.

2016-05-09clk: rockchip: drop old_rate calculation on pll rate changesHeiko Stuebner
Previously when everything happened in the set_rate callbacks itself we needed the old_rate value for the possible rate rollback, so that made it easy to also use it in the debug output. Now with the param-handling being done in separate functions, reading and recalculating the current pll rate only to use it in a debug message that won't get displayed in regular cases anyway is quite a waste. Therefore drop that value from the debug output. In the worst case that previous rate will have been displayed on the rate change before. Signed-off-by: Heiko Stuebner <heiko@sntech.de>
2016-05-09clk: rockchip: simplify GRF handling in pll clocksHeiko Stuebner
With the previous commit, the clock drivers now know at init time if the GRF regmap is available. That means if it isn't available then, it also won't become available later and we can therefore switch PLLs, that need the GRF for the lock-status, to read-only mode - similar behaviour as the aborting of rate changes we did before. This saves some conditionals on every rate change and we can also drop the rockchip_clk_get_grf function completely. Signed-off-by: Heiko Stuebner <heiko@sntech.de>
2016-05-09clk: rockchip: lookup General Register Files in rockchip_clk_initHeiko Stuebner
In the distant past syscons were initialized pretty late and weren't available at the time the clock init ran. As the GRF is mainly needed for PLL lock-status checking, we had this lazy init that tried to grab the syscon on PLL rate changes and denied these changes if it was not available. These days syscons are available very early and recent addition to rockchip clocks, like the PLL clk_init actually also rely on them being available at that time, so there is no need to keep that lazy init around, as it will also result in some more simplifications in other parts of the clock-code.

2016-05-09iommu: Allow selecting page sizes per domainRobin Murphy
Many IOMMUs support multiple page table formats, meaning that any given domain may only support a subset of the hardware page sizes presented in iommu_ops->pgsize_bitmap. There are also certain use-cases where the creator of a domain may want to control which page sizes are used, for example to force the use of hugepage mappings to reduce pagetable walk depth. To this end, add a per-domain pgsize_bitmap to represent the subset of page sizes actually in use, to make it possible for domains with different requirements to coexist.

2016-05-09staging: unisys: visorhba: main path needs to flow down the left marginTim Sell
In del_scsipending_ent(), the error-path and main-path were switched, so the error-path is handled like 'if (err) return;', and the main-path flows down the left margin. This also allowed us to remove the initialization of "sent".

2016-05-09staging: unisys: visorhba: fail gracefully for thread creation failuresTim Sell
Previously, if visorhba ever failed to create its thread, it would have subsequently attempted to do a kthread_stop() on an invalid task_struct pointer. This was fixed via the new visor_thread_stop() function, which validates the task_struct pointer before doing the kthread_stop(). Also, the other thread-related fields in visor_thread_info (has_stopped and id) were not being used, so visor_thead_info was just removed. We also now spit out an error message if thread creation fails.
